You love it or you hate it. You understand it or don't have a clue. Percents, percentage is a powerful tool to say about part of something. We made the Percentage calculator to make your life easier.

THIS IS ANCIENT VERSION OF CALCULLA.COM LEFT HERE FOR ARCHIVAL PURPOSES.ALL CALCULATORS SHOULD STILL WORK, BUT YOU CAN'T BE SURE. WE ALSO DON'T UPDATE THEM, SO EXPECT OUTDATED INFO.OUR SUGGESTION IS TO MOVE TO RECENT VERSION OF CALCULLA.COM BY CLICKING THE LINK: Resistors color codes

If you have unknown resistor read color pattern from it and put it to color table below (by clicking on cells). You get decoded resistor's parameters (resistance value, tolerance and - when you're using six strips pattern - temperature coefficent) in the result table on the bottom of the page.

If you know resistor's parameter and want to encode them into color strips pattern choose needed parameters in form below color table (resistance value, tolerance and temperature coefficent). Next, you will read colors pattern from schematic resistor's image or from color table (colors used in patterns are bordered).
